Pencampuran silika dan TiO2 dan penggunaan sebagai katalis telah diteliti. Tujuan dari penelitian ini adalah pengujian aktivitas fotokatalitik dari atap glasir silika/TiO2 untuk mendegradasi zat warna, seperti indigo carmine, rhodamin dan methyl yellow. Glasir dibuat dengan mencampur abu soda, boraks, serbuk kaca yang dikenal sebagai sumber silika dan TiO2 yang difungsikan sebagai fotokatalis. Pembakaran dilakukan dua kali pada 900°C. Aktivitas fotokatalis dari glasir yang dihasilkan dilakukan dengan uji kinerja degradasi menggunakan tiga pewarna berbeda. Pewarna dialirkan pada permukaan glasir silika / TiO2 selama 1, 2, 3, dan 4 jam. Perubahan konsentrasi zat warna diukur dengan spektrofotometer UV-VIS. Hasil penelitian menunjukkan produksi glasir genteng dapat dilakukan dengan menambahkan campuran TiO2 pada glasir. Hasil fotokatalitik menunjukkan degradasi indigo carmine adalah 74,58%, methanyl yellow 16,08% dan rhodamin 47,56%.

The sol gel process is one of the processes used in the manufacture of thin films on membranes because it can control the pore size in the resulting silica matrix. In addition, another way to build membrane size can be done by adding catalysts and precursors to be used. In this study, using a combination of tetraethyl ortho silicate (TEOS) and triethoxy vinyl silane (TEVS) precursors and citric acid as a catalyst to produce a silica matrix with mesoporous size so that it is suitable for application in the desalination process. The organo silica membrane was calcined at 350 C for 1 hour using the RTP calcination technique under vacuum, thus preventing the decomposition of carbon in the silica matrix. The membrane was dipcoated 4 times to obtain 4 layers. The FTIR (Fourier-transform Infrared Spectroscopy) test was carried out to see the functional groups on xerogel, namely silanol, siloxane and carbon. In addition, the performance of this membrane is carried out by desalination through pervaporation using 0.3% NaCl feed water with variations in feed air temperature, namely 25, 40and 60. The resulting flux of air value increased with increasing feed water temperature, namely 6.1; 11.2; and 12.1kg.m-2h-1while the resulting salt rejection was 99.72; 99.64 and 99.23%. So that the organo silica membrane is suitable when applied to the desalination process through pervaporation.

Bismuth oxide (Bi2O3) is a yellow solid, has good electrical properties and a wide band gap energy (2-3.96 eV). Therefore, this material is commonly used as a photocatalyst. This study aims to synthesize bismuth oxide using the sol-gel method, determine its physicochemical characteristics and photocatalytic activity in the degradation of methyl orange dyes. Bi2O3 is synthesized from Bi(NO3)3.5H2O which is reacted with citric acid at 100 ° C for 20 hours. The formed gel is then dried and calcined at 600 °C for 1, 2, 3, 4 and 5 hours. The synthesis results in the form of pale-yellow powder with the same crystal system that is a mixture of α-Bi2O3 (monoclinic) and γ-Bi2O3 (BCC) and has almost the same morphology that is similar to coral and has a particle size of 1-8 μm. The results of photocatalytic activity tests showed that the constant rate of degradation reaction of methyl orange by bismuth oxide with calcination time of 1, 2, 3, 4, and 5 hours respectively was 2.76×10-5 s-1, 2.65×10-5 s-1, 2.53×10-5 s-1, 2.81×10-5 s-1 and 3.87×10-5 s-1. Bismuth oxide with a calcination time of 5 hours has the highest photocatalytic activity. Meanwhile, bismuth oxide with a calcination time of 5 hours has a band-gap of 2.86 eV and 2.64 eV. The stages of decomposition of bismuth oxide material with a calcination time of 5 hours consisted of 3 release stages namely H2O, CO2, CxHyOz respectively 12.20%, 5.33% 30.54%.

This study aims to analyze the risk of occupational accidents occurring in the production section of PT. XYZ, an automotive manufacturing company. The risk analysis was conducted using the Job Safety Analysis (JSA) and Hazard Identification Risk Assessment (HIRA) methods. The primary data, which consists of occupational accident records from PT. XYZ, is secondary data indicating that in 2023, a total of 61 workplace accidents occurred. Additional data required to validate this research were obtained through literature review. The results of this study include a risk ranking that contains the risk values of occupational accidents obtained through the HIRA method and information on control efforts obtained through the JSA method. The conclusion drawn from the analysis shows that four types of workplace accidents are classified as low-risk, two types as medium-risk, and the control efforts for most types of accidents involve increasing worker awareness and supervision regarding the use of personal protective equipment (PPE) in accordance with standard operating procedures (SOPs), as part of fulfilling occupational health and safety (OHS) aspects in the company.
